<p>PROBLEM TO BE SOLVED: To provide a temperature control device for warming in which, even in the case where leak occurs in a polymer layer between a heating element wire and a temperature detection element wire, in spite of the temperature control device of a one-wire type cord-like heating wire, an OFF point of temperature control is corrected so as not to be at a high-temperature side over a preset value, overheat is prevented by performing control to prevent a temperature control part from outputting a heating signal, safety is secured and an economical property is also improved.SOLUTION: A correction capacitor is connected between both cathodes of two diodes of which the anodes are connected to both ends of a temperature detection element wire 4, and a positive electrode or a ground of a DC regulated power source driving the temperature control part. Thus, even in the case where leak of a polymer layer 3 is increased, a temperature signal voltage from the temperature detection element wire 4 can be corrected to be a voltage closer to a higher temperature than a temperature signal voltage in the case where there is no leak in the polymer layer 3.</p> |
